Margaret Courtney-Clarke has traveled to remote dwellings in the Transvaal to photograph the art of Ndebele women, whose murals are brilliantly colored, their geometrical symmetries embellished with old and new iconography and in a style that varies from woman to woman and house to house.

(A) whose murals are brilliantly colored, their geometrical symmetries embellished with old and new iconography and in a style that varies from woman to woman and house to house
(B) whose murals are brilliantly colored, their geometrical symmetries are embellished with old and new iconography, and their style is varying among women and houses
(C) whose murals are brilliantly colored, their geometrical symmetries are embellished with old and new iconography, and they are in styles that vary from woman to woman and house to house
(D) with murals brilliantly colored, their geometrical symmetries embellished with old and new iconography, and their style varies among women and houses
(E) with murals that are brilliantly colored, their geometrical symmetries embellished with old and new iconography, and their styles vary among women and houses

i can narrow it down to A and C
i dont think among women and houses is the right usage in this context.
In A and C, what is "their" modifying? murals or women..
In C, again what is "they" modifying? murals or women...
i have read on dictionary.com that "they" is used for referring to people..

but i think using *they* is redundant in C... if *their* refers to murals...then we are still talking about the murals in the latter half of the sentence...and we dont need to reference "murals" again.

What do you think? Explanations please?

Thanks

I don't find anything grammatically wrong with A. To me A sounds better. But, What is the correct answer ?

hmm... pretty vague even after close examination

Source of question and official answer/explanation please!
